# configure 腳本確定系統所具有一些特性，特別是 nginx 用來處理連接的方法。然後，它創建 Makefile 文件。
#
# configure 支持下面的選項：
#
# –prefix= <path& gt; - Nginx安裝路徑。如果沒有指定，默認爲 /usr/local/nginx。
#
# –sbin- path= - Nginx可執行文件安裝路徑。只能安裝時指定，如果沒有指定，默認爲 /sbin /nginx。

#
# 在不同版本間，選項可能會有些許變化，請總是使用 ./configure –help 命令來檢查一下當前的選項列表。
#
# 示例 (最好能在同一行)：
# ./configure \
# –sbin-path=/usr/local/nginx/nginx \
# –conf-path=/usr/local/nginx/nginx.conf \
# –pid-path=/usr/local/nginx/nginx.pid \
# –with-http_ssl_module \
# –with-pcre=../pcre-4.4 \
# –with-zlib=../zlib-1.1.3
# Example on Ubuntu/debian with libgcrypt11-dev, libpcre3-dev and libssl-dev installed (choose EITHER –with-md5 OR –with-sha1, but not both; on debian and ubuntu, they should both point to /usr/lib)
# ./configure –with-openssl=/usr/lib/ssl/ –with-md5=/usr/lib
# An Ubuntu Edgy .deb for version 0.5.2 can be found here: nginx_0.5.2-1_i386.deb.
#
# (NOTE: According to an October 2006 message md5 was used in a now broken http cache module and sha1 is used in an incomplete mysql library module and so are currently not needed.)
